西南大学“万无一虱”团队创新烟粉虱防控路径

Core Viewpoint - The "Wanwu Yishi" team from Southwest University has innovatively proposed a "dual-target prevention and control" system to address the challenges posed by the tobacco whitefly, a significant agricultural pest that can cause over 30% annual yield loss in solanaceous crops [1][3]. Group 1: Problem Identification - The tobacco whitefly is identified as a "super pest" that severely threatens agricultural production, particularly in eggplant and chili cultivation [1]. - Traditional chemical pesticide methods are becoming less effective year by year, leading to increased costs and ecological pollution, creating a dilemma for farmers [1]. Group 2: Innovative Solutions - The "Wanwu Yishi" team has developed a green technology for controlling tobacco whiteflies by combining theoretical research with practical application [3]. - The team has identified two core pain points: the strong mobility of the tobacco whitefly and the significant pollution caused by chemical pesticides [3]. - The innovative "internal and external dual-target" comprehensive prevention strategy has been proposed, targeting the pest's movement capabilities and reducing chemical pesticide reliance [3]. Group 3: Technological Advancements - The internal control utilizes advanced RNA interference (RNAi) technology to specifically target and silence key genes that control the movement of tobacco whiteflies, significantly reducing their activity and spread [3][5]. - The external control involves extracting effective natural insecticidal active ingredients from plants, which are environmentally friendly and have low residual risks, certified as "practically non-toxic" [5]. Group 4: Future Developments - The team has applied for 11 patents and published two papers in top-tier SCI journals [5]. - Collaboration with biotechnology companies is underway to promote the industrialization of the developed formulations, with plans to create smart monitoring devices and an AI pest warning platform for precise pesticide application [5].
